PAPER-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 302,228, dated July 22, 1884,

Application filed August 20, 1853. (No modeh) To all whom it may concern.-

Be it known that I, AUsrIN BASCOM, a citizen of the United States, and a resident of Bellefontaine, in the county of Logan and State 5 of Ohio, have invented a new and useful Improvement in Paper -Folding Machines, of which the following is a specification.

My invention consists of an improvement in paper-folding machines, and is briefly de-. scribed as follows, reference being had to accompanying drawings.

F'gure 1 is a perspective View of myinvention, showing my crank, the levers operating my feed-grippers, first-fold finger, delivery- I 5 rollers and belt operating the same, the lug on the pulley,which operates the blade that feeds the papers to the delivery-rollers, and the paper-receiver. Fig. 2 is a perspective view showing the feed-grippers, the three foldingfingers, the ways in which the papers are folded, the rack and segment-gear that operate the second-folding finger, the pulleys and belt operating the delivery-rollers, and the cam-tappet which raises the fly to pile the papers on 2 5 the receiving-table. Fig. 3 is a top sectional View showing the main shaft, the rack and segment that operates the second-folding finger and, through the connectingrod and pivoted arm, the third-folding finger, the lug that operates the blade to feed the paper into the rollers for the last fold, the delivery and pressing rollers, and the cam-tappet which raises the fly of the receiving-table to pile the papers on the table. Fig. at is an enlarged view of my feedgrippers.

A, Fig. 3, are the first ways, down which the paper isdoubled for the first fold; B, the second ways, for the second fold; .(l, the third ways; D, the delivering and pressing rollers;

40 113, first-fold finger; F, second-fold finger on arm F, having segment N on the other end; G, third-fold finger; H, blade, which makes fourth fold and presents it to the pressing and delivery rollers; I, main shaft; K, crank on main shaft; L, connecting-rod; M, rack; N, segment-gear; P, connecting-arm, pivoted at O to segment N and to the pivoted arm Q, to give the necessary movement to finger G; R, pivoted point of arm Q,- S, lug on pulley T,

which strikes the bent arm U on the under side at the proper time to cause blade H to force the paper between thedelivery-rollers. The arm U is retracted by a spring. V, beltpulley on axis of rollersD; \V, crank on main shaft, operating the levers'which actuate the first-fold finger and the feed-grippers;'X Y Z, arms, which, through crank \V, operate the slide a, carrying fold-finger E, and playing on standard b; c, connecting-rod fromcrank W, to operate lever d, which actnates the gripper-carrier f,- c. rod on which gripper-carrier plays; g, the feed-grippers; h, roller on which grippers rest, and which has a partial revolution; t'lc, stops to limit the amount of revolution of roller h,- Z, pro- 6 jecting arm on standard I), carrying steadying-ways m, in which the first-fold finger plays when above the table; 0, tappet on main shaft, which strikes the lug p to raise the fly q of the receiving-table and pile the papers against the sliding rack r.

The operation isas follows: The paper is fed to the grippers supported on roller h, which has a partial revolution limited by stops t" and k. In the forward movement the revolution of 7 5 the roller opens the grippers, which close on the paper as the roller revolves on its backward movement, and carry it back until the middle of the paper is immediately over the way A. The first finger, E, descending, d0u- 8o bles the paper and carries it down the proper depth, across the path of finger F, and returns. As'finger E leaves the ways in its ascent the finger F, moving in the are of a circle, strikes the paper in the middle of its length and carries it across the path of finger G, so that the middle of the paper will be immediately across said path. As finger F in its return crosses the path of finger G, the finger G moves for ward also in the arc of a circle, striking the paper in the middle, carrying it between the ways 0 and across the path of blade H, making the third fold. As finger G returns on its path,

the blade H strikes the paper in the middle of its length, doubles it, and presents it to the delivery and pressing rollers D,that drop it on the fly of the receiving-table. The tappet 0 on the fly, main shaft then strikes the lug p of the raising the fly to a standing position, and pi ling the papers against the sliding rack 1', which recedes as the papers are piled against it, be-

ing clasped on the table and held by a spring. As the third-folding finger strikes one paper in folding, the first finger is making the first fold of another, and the rollers are delivering another on the receiving-table, each fingerhaving barely time to reach its starting-point be fore starting forward again. My ways are lined or wound with listing or similar material to prevent the papers tearing against the edges, and to prevent their being drawn out with the fingers on their return.

One of the crank-arms NV and the arm K (both of them on the main shaft) are slotted, so that by varying the position of the bolt or crank-pin, thus shortening or lengthening the crank-arm, the movements of the machine are adapted to differentsized papers.

The fly q of the receiving-table is simply a hinged leaf whose normal position is at an angle of about forty-five degrees just in front of and beneath the rolls D. The paper as it passes from the rolls drops upon the inclined table and slides onto the fiy,which is raised to pile the papers by the tappet 0 on the main shaft striking under the lug p on the fly. As soon as the tappet 0 passes the lug, the fly falls back into position to receive another paper.

The slots in cranksK and XV are for the purpose of regulating the amount of throw or play of the foldingfingers to suit diiferent-sized papers.

That I claim is- 1. The combination, with the ways A B O, (the ways B 0 being in the arc of a circle,) of the fingers E F G, the path of the fingers F G being in the are of a circle, as and for the purpose set forth.

2. In combination with the folding-fingers and operating devices of a folding-machine, the slotted cranks K and W. by which the amount of throw of all the folding-fingers is regulated.

3. The combination,with the folding devices of a folding-machine. of feed-grippers g, having roller h, stops 1 7c, and the carrier f, substantially as set forth.

4. The combination,with the folding-fingers F G, of the crank K, rod L, rack M, segment N, and arms F P Q, as and for the purpose set forth.
